Legislation and tax-credit debates around carbon capture

Recent developments in carbon capture legislation and market dynamics underscore the intricate challenges and opportunities facing U.S. climate policy. As policymakers grapple with refining incentives like the 45Q tax credit, new legislative proposals, private-sector investments, and evolving voluntary carbon markets are shaping a more nuanced and ambitious carbon removal landscape.

Legislative Advances: Representative Bonamici’s H.R. 7656

Building on ongoing debates around the effectiveness of current carbon capture incentives, Representative Suzanne Bonamici’s H.R. 7656, the “Removing and Sequestering Carbon Unleashed in the Environment Act,” proposes an expanded and more integrated federal approach to carbon removal. This bill aims to address key shortcomings identified in the 45Q tax credit framework by:

• Enhancing funding mechanisms that support a broader array of carbon removal projects, including emerging technologies beyond traditional CCS
• Strengthening measurement, reporting, and verification (MRV) standards to ensure that claimed carbon sequestration is accurate and transparent
• Promoting federal coordination to overcome infrastructure bottlenecks and accelerate technology deployment across sectors

By moving beyond purely financial incentives, H.R. 7656 reflects a growing recognition that policy clarity, regulatory consistency, and infrastructure development are essential pillars for scaling carbon removal effectively.

Persistent Critiques of the 45Q Tax Credit

Despite its role as a cornerstone of federal carbon capture policy, the 45Q tax credit continues to face criticism for limitations that may hinder its long-term impact:

• Broad eligibility criteria allow projects with questionable net carbon removal benefits to qualify, diluting the environmental integrity of the program
• The credit's design often leads to disproportionate financial gains for incumbent fossil fuel companies, raising concerns about market distortions and insufficient support for innovative removal technologies
• Valuation complexity and uncertainty surrounding credit monetization create challenges for project developers in securing financing and planning long-term investments
• The program lacks integration with complementary policies, such as infrastructure build-out and robust carbon markets, which are crucial for translating incentives into real-world emissions reductions

An industry analyst described the credit metaphorically as “catching fog with a tweezer,” emphasizing that the scale and precision of incentives need to improve significantly to meet climate goals.

Market and Industry Developments: Private Sector Momentum and Voluntary Market Dynamics

Amid policy debates, the private sector is actively advancing carbon capture deployment, signaling both opportunity and complexity:

• Occidental Petroleum’s partnership with Warren Buffett’s Berkshire Hathaway, which acquired a 29% stake in Occidental’s carbon capture operations, highlights growing investor confidence in large-scale CCS projects. Occidental is developing what is projected to be the world’s largest carbon capture plant, aiming to capture millions of tons of CO₂ annually and demonstrating the potential for industrial-scale removal.
• The North American Biocarbon Conference, set to debut in 2026, will focus on the burgeoning biocarbon sector, exploring emerging markets, project pathways, and the role of biological carbon removal technologies. This event underscores the expanding diversity of carbon removal approaches beyond geological sequestration.
• Meanwhile, voluntary carbon markets face ongoing scrutiny regarding credit quality and verification standards. The simple premise of “one credit equals one tonne of CO₂ removed” is complicated by concerns over additionality, permanence, and double-counting. These quality questions directly influence market demand and price signals, affecting the viability of carbon removal projects and their ability to attract investment.

These developments illustrate that while market forces are mobilizing capital and innovation, robust governance and quality assurance remain critical to ensure that investments translate into genuine climate benefits.

Significance for Policy Design and Climate Strategy

The confluence of legislative proposals, industry investments, and market challenges highlights several key lessons for carbon removal policy:

• Calibrated incentives must be tied to verifiable carbon removal outcomes, avoiding windfalls and ensuring that financial support drives real emissions reductions.
• Clear and stable regulatory frameworks are essential to provide investment certainty and foster innovation across diverse carbon removal technologies.
• Complementary policies—such as infrastructure development, MRV standards, and credible carbon markets—must be integrated to amplify the impact of tax credits and other financial incentives.
• Legislative efforts like H.R. 7656 represent a promising shift towards a more holistic approach, recognizing that financial incentives alone are insufficient without addressing practical barriers and ensuring environmental integrity.

Conclusion

The debate and legislative activity surrounding carbon capture and the 45Q tax credit reflect the broader challenge of scaling carbon removal to meet ambitious climate targets. Recent developments—from Representative Bonamici’s comprehensive bill to high-profile private-sector investments and emerging biocarbon markets—signal a maturing field moving toward greater sophistication and impact.

However, as the voluntary carbon market quality debates and critiques of existing incentives underscore, policy design must evolve to ensure that incentives lead to real, measurable climate benefits rather than subsidizing incremental or speculative efforts. The future of carbon capture policy will hinge on balancing economic incentives with rigorous environmental standards and coordinated infrastructure planning—an imperative that legislators, industry, and markets are increasingly recognizing.

As these dynamics unfold, the U.S. carbon removal strategy will likely serve as a bellwether for global efforts to harness technology and markets in the fight against climate change.
